  • Publication number: 20200363571
    Abstract: A transparent substrate with an antiglare film, includes a transparent substrate having first and second main surfaces and an antiglare film formed on the first main surface. The antiglare film includes a low refractive index layer formed on the first main surface and a high refractive index layer formed in the low refractive index layer and having a refractive index different from that of the low refractive index layer. The low refractive index layer has nlow of 1.4 to 1.8. The high refractive index layer has nhigh at least 0.1 higher than the nlow. The high refractive index layer has an area ratio of its portion where a surface inclination to the first main surface is 0.5° or less of 15% or less. An average length RSm of elements of a roughness curve of an outermost surface on a first main surface side is 50 ?m or less.

  • Publication number: 20150338551
    Abstract: A transparent base has a first surface that is textured, and a second surface that is textured and is located on an opposite side of the transparent base from the first surface. A 20° effective reflected image diffusion index value Rb20° and a 45° effective reflected diffusion index value Rb45° used for evaluation of the first and second surfaces satisfy a relationship Rb20°?Rb45°>=0.05.

  • Publication number: 20140261677
    Abstract: A laminated structure includes an anti-reflection structure having periodic concavo-convex parts on a surface thereof, and a transparent conductive layer formed on the concavo-convex parts. An arbitrary convex part, excluding a convex part located at an outermost side, and six convex parts having distances from the arbitrary convex part that amount to a smallest sum, are arranged to satisfy a condition requiring a connecting part to exist between the arbitrary convex part and each of four convex parts amongst the six convex parts, and a condition requiring a concave part to exist between the arbitrary convex part and each of two remaining convex parts amongst the six convex parts.

  • Publication number: 20040105053
    Abstract: A composite display device comprising a first display member 1 and a second display member disposed between the first display member 1 and an observer 14 wherein the second display member is an electro-optical element 2 which transmits light under application of no voltage and scatters light under application of a voltage, and the composite display device is clear and provides a feeling of open air in an unused state: allows an observer to see simultaneously a background scenery and a display effected by the electro-optical element in a used state, and provides to an observer an impression that a picture image is suspended in space.
